Worn clutch isn't grounds for warranty repair (unless you're an extreme case).
Anyway, what kind of driveway do you have? Is it a fairly steep hill and your wife either rode the clutch up the driveway, or revved it to 4k and dumped the clutch? If this is the case, your clutch is probably fine, and just make sure you stop at the bottom of the driveway, open the garage door and have the clutch fully engage before you make it onto the driveway.
